METHOD AND APPARATUS FOR TESTING DESIGN OF SATELLITE WIRING HARNESS AND SIGNAL PROCESSING UNITS

A method of testing designs of wiring harnesses (104) includes generating a virtual electrical system (206) including virtual wiring harnesses (302) that interconnect virtual modules (304) of communications circuitry including signal sources (306) and signal destinations (308). The method also includes testing signal pathways (312) and thereby the virtual wiring harnesses (302). The testing includes generating a simulated signal that is input to a specific electrical connection at a signal source (306) and routed through a signal pathway (312) to a specific electrical connection (310) to a signal destination (308). The testing includes verifying receipt of the simulated signal by the specific electrical connections via the signal pathway (312). And in an instance in which receipt is not verified, the testing includes identifying a particular electrical connection at which an error occurred in the receipt of the simulated signal, and a particular virtual wiring harness and a particular virtual module respectively connected to and including the particular electrical connection.
